CVE-2026-4395

Heap-based buffer overflow in the KCAPI ECC code path of wceccimportx963ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkeyraw buffer via a crafted oversized EC public key point. The WOLFSSLKCAPIECC code path copies the input to...

CVE-2019-14317

wolfSSL and wolfCrypt 4.1.0 and earlier formerly known as CyaSSL generate biased DSA nonces. This allows a remote attacker to compute the long term private key from several hundred DSA signatures via a lattice attack. The issue occurs because dsa.c fixes two bits of the generated nonces...

DEBIAN-CVE-2019-13628

wolfSSL and wolfCrypt 4.0.0 and earlier when configured without --enable-fpecc, --enable-sp, or --enable-sp-math contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about th...
